Title: The cast sleigh motor 1684
Post by: T-man on May 23, 2024, 08:33:22 PM

For this motor I am interested in part numbers for the double reduction motor intermediate gears and wheels.
I have the frame but do not know exactly what engine it was in originally. I have found other engines with the same single reduction motor, but I cannot find one with a double reduction gearing.

Thanks for any information.

One problem I had was matching up the motor to the engine number. After all the views, I revisited the postwar manual and found the 1655 which has the double reduction gear. Made in 1948. The wheels are geared differently from the 1654. I know the gear is a 1655m-5. Page 122 of the Greenberg Repair Manual.

The 1960 revision to the loco 1655 page of the service manual says to use 1655m-7 which is a "cluster gear." Cluster gear means there are two gears stacked together as one part. The earlier m-5 was no longer availible in Oct. 1960.

The wheels are 1655m-18 gear wheel with axle and 1656M-11 plain wheel. Note plain wheel # is 1656 not 55.

Thanks,
 I see the alternate number on the page.
 I did notice the cluster gear from the picture. Now I can move forward to get this motor running.
